After a few months of closed testing, Valve has released a public beta version of Steam with In-Home Streaming enabled. In-Home Streaming allows you to stream any game from a host PC to a client (a Mac laptop or wimpy Windows netbook, for example). This will eventually be a key feature that allows for cheap, low-power Steam Machines in the living room that can stream games from a more powerful gaming PC. Read on for our hands-on impressions, and a video demo of me streaming Dark Souls 2 to my laptop while sitting on the toilet.
